1. A method, comprising:
- a first network device consolidating Ethernet Alarm Indication Signal (ETH-AIS) information corresponding to a plurality of Virtual Local Area Networks (VLANs) into a single Ethernet frame;
sending, by the first network device, the Ethernet frame to a second network device over a communications link carrying traffic for the plurality of VLANs;
receiving the Ethernet frame by a second network device on a particular port of a plurality of ports of the second network device; and
sending, by the second network device, ETH-AIS information of said received consolidated ETH-AIS information corresponding to each particular VLAN of the plurality of VLANs out each port of the plurality of ports configured for sending packets for the particular VLAN except for the particular port on which said consolidated ETH-AIS information was received;
wherein said consolidating ETH-AIS information of the plurality of VLANs refers to combining individual ETH-AIS information of each of the plurality of VLANs into the single Ethernet frame sent to peer devices rather than sending separately in different Ethernet frames.

Abstract
Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.

13. An apparatus, comprising:
-
a plurality of ports configured for communicating over a plurality of links; one or more processors and one or more memories;
wherein said one or more processors are configured to perform operations, with said operations including;consolidating Ethernet Alarm Indication Signal (ETH-AIS) information corresponding to a plurality of Virtual Local Area Networks (VLANs) into a single Ethernet frame; and sending the Ethernet frame from one of the plurality of ports over a communications link carrying traffic for the plurality of VLANs thereby providing the corresponding ETH-AIS information to one or more devices in each of the plurality of VLANs; wherein said consolidating ETH-AIS information of the plurality of VLANs refers to combining individual ETH-AIS information of each of the plurality of VLANs into the single Ethernet frame sent to peer devices rather than sending separately in different Ethernet frames. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus, comprising:
-
a plurality of ports configured for communicating over a plurality of links; one or more processors and one or more memories;
wherein said one or more processors are configured to perform operations, with said operations including;receiving, on a particular port of the plurality of ports, an Ethernet frame including consolidated Ethernet Alarm Indication Signal (ETH-AIS) information corresponding to a plurality of Virtual Local Area Networks (VLANs); and sending ETH-AIS information of said received consolidated ETH-AIS information corresponding to each particular VLAN of the plurality of VLANs out each port of the plurality of ports configured for sending packets for the particular VLAN except for the particular port; wherein said consolidated ETH-AIS information of the plurality of VLANs refers to combined individual ETH-AIS information of each of the plurality of VLANs into a single Ethernet frame sent to peer devices rather than sending separately in different Ethernet frames. - View Dependent Claims (19, 20)
